HYDRALiLIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 627,925, dated June 2'7, 1899.

Application filed March 9, 1899. Seria1ll0- 708,387. (No model.)

To all whom it may concern: I

Be it known that I, FERDINAND J. HAGEN,

a citizen of the United States, residing in New York city, State of New York, have invented certain new and useful Improvements in Hydraulic Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of the'invention is to provide a hydraulic apparatus adapted to store up and utilize for industrial purposes the varying energy ofsuch powers as wave and tide powers, as more fully hereinafter set forth.

Figure 1 is a side elevation of my apparatus, partly in section; Fig. 2, a plan thereof, and Fig. 3 is a detail section of the reducingvalve.

Referring to the drawings by letters, a and b designate suitable pumps, preferably adapted to be operated by a wave and tide motor and for that reason located near a natural body of water. The suction heads or pipes c of the pumps enter a large main water-supply tank d, and their outlet-pipes e and f, respectively, are provided with check-valves g and h, respectively, and are connected to a common pipe 2', this pipe t' being provided with suitable stop-cocks or valvesj, k, and Z, the connecting-pipe f being provided with an additional valve m. The pump 19 is also connected to an adjacent water-supply by means pf a pipe 72, which is provided with a cock 0 and check-valve 13.

One end of pipe t'enters a main storage or pressure tank q, and its other end empties into an elevated tank r, and said pipe is provided near reservoir q with a check-valve s. The pressure-tank q is connected by a pipe 15 with tank 61 and is provided with a pressure-regulator 10, whereby excess of pressure in tank qwill automatically relieve itself and empty the water into tank cl. The exitpipe '1; from tank q is provided with a pressure-regulator or reducing-valve w and is connected at its other end to pipe 2', a suit able stop-cock 00 being inserted in pipe 1) near where it'enters said pipe 2'. Connected to the pipe '1) at intervalsare a series of two or more auxiliary pressure-tanks g, each connected by an independent pipe provided with check-valves and stop-cocks z and ct, respectively. These auxiliary tanks are provided with valved exit-nozzles 1), adapted to direct a jet of water under pressure upon small water-wheels or turbines c, the water from these Wheels being received in a tank 61, provided at one endwith a spout which directsthe water upon a large water-wheel f, journaled below storage-tank r and above supply-tank 1, into which latter tank the water from the large water w'heel is emptiedafter it has spentits force of gravity upon said wheel.

The pressure-regulator or reducing-valve w is set to close when a predetermined pressure has been reached in the tanks y and prevent the further-passage of water to said tanks until the pressure therein has been reduced. By this means the pressure in the auxiliary tanksy will be maintained uniform as long as the pressure in the main tank is'equal to or exceeds the predetermined pressure in the auxiliary tanks, while the pressure in the main tank may vary with the varying power of the motor operating the pumps. By this means wheel 0- will be driven by a uniform The storage-tank r is provided with a depending valved nozzle g, adapted to direct the water from said tank into water-wheel f, and the valve in nozzle g is automatically controlled by a governor h, operated from the shaft of the Water-wheel, whereby the speed of the water-wheel will automatically regulate the quantity of the water from tank 1'.

The shafts of the smallwatenwheel c and large wheel f may be connected up to a common shaft Z by suitable belts j, the main shaft being provided-with suitable clutches IOO of a lever a", upon the long arm of which an adjustable weight is mounted. When the desired pressure in the tanks 3 is reached, the diaphragm c is depressed and valve (2" closed. By means of the weight on lever a this valve may be caused to close at any desired pressure.

This hydraulic system is especially design ed for use in connection with a wave-motor of the class covered by my Patent No. 616,615, granted December 27,1898,in which,of course, the power that can be utilized varies very greatlyas the activity of the waves varies. In connection with motors, such as wave-motors, where the supply of energy so greatly and constantly varies, it is especially necessary that means be provided which will store up and utilize to the greatest possible extent this constantly-varying force, the apparatus requiring to adjust itself instantly and utilize to the fullest extent the minimum of energy to be obtained from the wave, aswell as the maximum of energy to be obtained therefrom.

It is believed that in my present invention I have provided an apparatus that will thus provide for the storing up of the surplus of the waves, to be utilized when they become too quiet to afiord the desired average of power, whereby the power supplied to the transmitting machinery will be substantially uniform should it be desiredto impart all the power to a single shaft or machine.

It will be observed that pump b not only serves to supply through pipe 17. the proper amountof water for the proper working of the system, but also is adapted to lend its aid to main pump a in filling tank rand keeping up the pressure in the several pressure-tan ks. While twopumps are desirable when a motor of the variety shown in my former patent is employed, it is of course understood that a single pump may be employed, if desired. It will also be observed that any number of auxiliary pressure-tanks may be employed, according to the nature of the natural body of water whose waves the apparatus is de signed to utilize. It will be observed that by the system of pipes and valves shown allthe power may be applied to the main Waterwheel f or it may be distributed to. the series of auxiliary water-wheels, as occasion may require. i

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a hydraulic apparatus, the combination of a pressure-tank, a force-pump for forcing Water thereinto, a valved nozzle connected to said tank, an auxiliary water-wheel adjacentsaid nozzle, a tank to receive the spent water for said auxiliary wheel, a main waterwheel adapted to receive the water from said tank, a storage-tank above said main waterwheel, a valved outlet from the tank to the main Water-wheel, a governor operated by the water-Wheel and controlling the valved outlet from the storage-tank, a valved pipe connecting the storage-tank to the pump, whereby the storage-tank may be supplied from the pump and the pressure kept up in the pressure-tank by the pump andwhereby also the valved outlet of the storage-tank will be automatically opened when the spent Water is insufficient to operate the main waterwheel at the desired speed, making up the deficiency from said storage-tank.

2. In combination a main water-supply, a pump connected thereto, a main pressuretank connected to said pump by valved piping, a storage-reservoir '1" connected to the pump by valved piping, a series of auxiliary pressure-tanks connected to the main pressure-tank, an automatic regulator or pressure-reducing valve between the main and auxiliary pressure-tanks to maintain a uniform pressure in the auxiliary tanks, waterwheels adapted to be operatedby the auxiliary tanks, a main water-wheel, and means adapted to convey the waste Water from the auxiliary wheels to said main wheel.

3. The combination of a main water-supply tank, a main pump connected thereto, an auxiliary pump connected to said tank and to a source of supply, a pressure-tank q, a storage-tank r, valved piping connecting said tanksto both pumps, a pipe u connecting the tank q to tank 0", a series of auxiliary pressure-tanks connected to pipe '0, a waterwheel for each of said tanks, a main waterwheel, means for conveying the waste water from the auxiliary wheels to the main wheel, a valved outlet from the tank '2", and means operated by the main water-wheel to control said valved outlet, whereby when the volume of waste water from the auxiliary waterwheels is not suflicient to drive the main wheel at the desired speed water will flow from the tank 9" to said wheel.

In testimony whereof I hereunto aifix my signature, in the presence of two witnesses, this 20th day of February, 1899.

FERDINAND J. HAGEN.
